The DBH 8719 oil seal is a radial shaft seal with a 51 mm shaft diameter, 58 mm housing diameter and 4 mm height, with an Mt design. It is used to retain lubricant and exclude contaminants in rotating equipment, with the shaft turning and the sealing surface seated against the housing. It is a wear part that should be replaced when oil leakage or dirt ingress appears. MR Accesorios Industriales carries this brand and advises you on choosing the right oil seal.

The DBH 8719 is a single-lip radial shaft seal, identified by its designation 8719. Its dimensions are 51 mm shaft diameter, 58 mm housing diameter and 4.00 mm height. The Mt design corresponds to a configuration with a sealing lip and metal body, suitable for press-fit mounting in the housing. This combination of dimensions and design makes it suitable for reduced axial spaces, where a compact seal is needed to work on the shaft and against the housing.

Typical applications for this oil seal include gearboxes, pumps, electric motors, rollers and transmission equipment where there is a rotating shaft that must be sealed against oil or grease loss. It is also used to prevent the ingress of dust, water or particles into bearings and gears. Because of its 4 mm height, it is common in assemblies where axial space is limited and a low-profile seal is required.

To install the DBH 8719 oil seal, verify that the shaft diameter is 51 mm and the housing is 58 mm, with 4 mm of height available. The shaft surface must be clean, free of burrs or marks, and lubricated before sliding the seal on. The lip must face the side of the fluid to be retained. If the shaft shows wear, consider a neighboring size or a seal with the lip in another position. Correct alignment between shaft and housing prevents premature leaks.
